El intercambio

When Caroline and Francis receive an offer to exchange their home, they don't hesitate. They are working hard to put their marriage back together and a week alone may be just what they need. When they open the door they find a somewhat sinister and almost empty place. It is difficult to imagine who could live there. However, gradually, Caroline begins to discover some traces of life... of her own life. The flowers in the bathroom or the choice of music CDs might seem innocent to her husband's eyes but to her they are just the opposite: they are clues. It is as if the person with whom they have exchanged housing is someone she knows, someone she wants to forget. But that person is now at home...
